Apt should be enforcing that the versions of the i386 and amd64
multiarch packages are in sync; so if a different version of
libudev1:i386 is installed, this would be a bug in apt.

But if the libudev1:i386 comes from a different source than the Ubuntu
archive, it could have the same package version but not have the correct
contents (in particular, the Ubuntu-specific changelog filtering which
is done in Launchpad).

To fix up the system once in this state, you may need to do a `sudo rm
/usr/share/doc/libudev1/changelog.Debian.gz` and then reinstall
libudev1:amd64.  But this doesn't guarantee that libudev1:i386 is in a
correct state or that it will continue to work correctly on future
upgrades; for that you need to figure out the root cause of
libudev1:i386's changelog not being in sync.
